COURSE OVERVIEW:

Tight reservoirs present unique challenges for reservoir characterization, well planning, and development due to their low porosity, ultra-low permeability, complex pore systems, and strong heterogeneity. Conventional petrophysical workflows are often insufficient to describe flow behavior, predict productivity, or support stimulation design in such formations. This course provides a comprehensive and advanced treatment of petrophysical analysis tailored specifically to tight clastic and carbonate reservoirs.

Participants will review the geological and rock physics foundations of tight reservoirs, including pore structure, micro-porosity, natural fractures, and the impact of diagenesis on reservoir quality. The course covers advanced logging technologies and interpretation techniques such as high-resolution resistivity, nuclear magnetic resonance (NMR), dielectric logs, borehole imaging, and multi-mineral evaluation for complex lithologies.

Special emphasis is placed on integrating core and log data, designing and interpreting special core analysis (SCAL) programs, deriving capillary pressure and relative permeability functions, and building robust saturation and permeability models in the presence of strong capillary effects. The course also explores how advanced petrophysical products feed into geocellular models, geomechanics, hydraulic fracturing design, well completion strategies, and sweet spot identification. Real field examples and exercises are used throughout to illustrate workflows and best practices for tight reservoir development.

COURSE OBJECTIVES:

After completion of the course, the participants will be able to:

• Describe the defining characteristics of tight reservoirs and their implications for petrophysical analysis and reservoir performance.
• Differentiate between tight clastic and tight carbonate systems in terms of pore structure, diagenesis, and flow mechanisms.
• Identify the main data sources for tight reservoir characterization, including logs, core, SCAL, and production data, and assess their quality and limitations.
• Apply advanced conventional log interpretation techniques adapted for low porosity and low resistivity contrast environments.
• Explain the principles of NMR logging and use NMR outputs (T2 distributions, bound and free fluids) for improved porosity, permeability, and saturation interpretation in tight rocks.
• Interpret borehole image logs to characterize natural fractures, breakouts, in situ stress orientation, and their impact on flow and stimulation.
• Design and evaluate special core analysis programs for tight reservoirs, including relative permeability, capillary pressure, and wettability measurements.
• Build integrated porosity and permeability models in tight formations using combined core, NMR, and image log information.
• Develop saturation models that correctly handle strong capillary pressure effects, transition zones, and low resistivity pay in tight reservoirs.
• Assess the impact of rock mechanical properties and geomechanics on petrophysical evaluation, frac design, and wellbore stability.
• Integrate petrophysical results into static and dynamic reservoir models to support resource estimation and production forecasting in tight reservoirs.
• Apply petrophysical workflows to identify sweet spots, high-quality intervals, and target zones for horizontal wells and multistage fracturing.
• Evaluate uncertainty in petrophysical parameters and propagate it into volumetric and development planning decisions.
• Critically review vendor deliverables and third-party studies for tight reservoir petrophysics, ensuring consistency and technical robustness.
• Use case studies and practical examples to construct advanced, fit-for-purpose petrophysical workflows for their own tight reservoir assets.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive but practical and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material through PowerPoint equipped with necessary animation, learning videos, and general discussions will be provided.

The course participants shall be evaluated before, during, and after the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants who complete at least 80% of the total attendance time requirement.
